Doosan Lathe LYNX 220M

Procedure : 1) Loosen the headstock clamping screws(M20, 5 pcs.).

• After loosening the adjusting screw(b), secure the adjusting screw(a). This shifts the headstock in the A direction.

• After loosening the adjusting screw(a), secure the adjusting screw(b). This shifts the headstock in the B direction.

• Carry out this adjustment while reading the dial indicator applied at the front end of the test piece.

c) After the required accuracy is obtained, tighten the 5 screws for headstock clamping. Note that reading of the dial indicator applied at the test piece top end must not change.;

Warning: Ensure the pump is turned off before starting the cleaning process.

Cover at the side of the coolant pump removed

Coolant drawn out of the tank by the pump

Coolant tank pulled out to the right until the pump protrudes from the side cover

Coolant tank pulled out to the front

Inside of the coolant tank cleaned

Coolant tank reinstalled correctly

Caution: The coolant tank must not protrude from the front rail. If the coolant tank is not installed correctly, coolant will leak.

NOTICE! The machine should be completely and correctly lubricated in strict adherence to the directions in the Lubrication Chart in the following page.

Is the specified lubrication oil used?

Is the amount of lubricating oil and its discharge condition checked everyday?

Note 1: We do not have any experience in using the oils other than those indicated by an asterisk(*). Selection should thus be made from them. Because slide-way lubricating oil contains additives such as extreme-pressure additive, it could incur variety of troubles if reacting with other oils or coolant. Therefore, pay special attention to the use of slide way lubricating oil.

Note 2: As for service point or amount of lubricating oil of the machine, refer to the Instruction Manual of respective machine models.

Note 3 : Lubricating oil used in common with coolant or lubricating oil used in common with hydraulic oil might cause corrosion of lubrication unit or turbidness of oils to result in lubrication failure, which, in turn, leads to damages on the slideway surface or ball screw. (We take no responsibility for the troubles caused by using the lubricating oil which is not our recommendation.)

Note 4: As for oil replenishment for the optional accessories such as special chucks or chip conveyor, refer to the Special Instruction Manual supplied with individual accessories.

Note 5: When slideway lubricating oil mixed with coolant and some trouble appears, contact your local DOOSAN Infracore representatives. They have optional accessories such as oil skimmer.

Check the wipers for abnormalities such as damage

Check for oil leakage and for damaged piping

Check the Air unit element and if necessary, replace

Check the electrical components for dirt and discoloration and check for loose terminal screws

Check for loose connector/terminals between units

Sign off on the 6 Monthly Lathe Inspection

• The machine is shipped after complete adjustment of tapered gibs. Readjustment will become necessary when the gibs are worn or loosened by use, resulting in noticeable irregular feed movement, which adversely affects the working accuracy.

• Adjust the gib using the adjusting screws on right side of the saddle after removing the right and left saddle wipers.

a) Loosen the gib adjusting screw at counterclockwise(CCW).

b) Fully tighten at clockwise(CW) and then return by a half turn the gib adjusting screw.

c) Tighten the gib adjusting screw at clockwise(CW).

• Target clearance should be 0.01 mm (0.0004 in.).

d) Adjust the gib of tailstock in the same method.;
